COUPLING AND CONTROL ASSEMBLY INCLUDING A NON-CONTACT, LINEAR INDUCTIVE POSITION SENSOR
A coupling and control assembly including a non-contact, linear inductive position sensor is provided. The assembly includes a coupling housing and a stator structure disposed within the coupling housing and including a stator housing. A translator structure is coupled to a coupling member of the assembly to rotate therewith about a rotational axis. The sensor is mounted on one of the housings. The translator structure includes a coupler element made of an electrically conductive material. The sensor is configured to create a magnetic field to induce eddy currents in the electrically conductive material. Movement of the coupler element changes a magnetic field caused by the eddy currents. The sensor provides a position feedback signal for vehicle transmission control. The signal is correlated with the linear position of the translator structure along the rotational axis.
SWITCHABLE ONE-WAY CLUTCH
A one-way clutch, including: a case; a drive plate enclosed by the case and defining openings; a first plate non-rotatably connected to the case and defining a first opening; a rotatable actuator plate; a strut including a central portion, an engagement portion, and a control portion; and a spring. In a locked mode: the spring pivots the engagement portion into an opening of the drive plate, a rotation of the drive plate in a first direction is enabled, and a rotation of the drive plate in a second direction is blocked. To transition from the locked mode to a free-wheel mode, in which the rotation of the drive plate in the second direction is enabled, the actuator plate is rotated by an actuator to contact the control portion and pivot the strut to displace the engagement portion out of the opening of the drive plate.
Clutch and vehicle motive power transmission structure
Provided is a clutch that is able to not only transmit torque smoothly even when an input shaft and an output shaft significantly differ in relative speed and phase, but also reduce an energy loss during torque transmission. The clutch (10) includes a dog clutch (40) for transmitting forward or reverse torque from the input shaft (11) to the output shaft (12), and a friction clutch (20) for transmitting torque from the input shaft (11) to the output shaft (12) and disposed in parallel with the dog clutch (40), and selectively transmits or interrupts torque between the input shaft (11) and the output shaft (12).
Dog clutch with ratcheting one-way clutch
A dog clutch with ratcheting one-way clutch includes an axis, a dog clutch ring, a first ring, a second ring, and a plurality of rockers. The dog clutch ring has a plurality of first teeth. The first ring includes a plurality of second teeth, complementary to the first teeth, a first spline for receiving a first shaft, and a plurality of first pockets. The second ring includes a plurality of third teeth, complementary to the first teeth, a second spline for receiving a second shaft, and a plurality of second pockets. The plurality of rockers is disposed in a one of the plurality of first pockets or the plurality of second pockets for selectively engaging with the other one of the plurality of first pockets or the plurality of second pockets to prevent rotation of the first ring relative to the second ring in only one rotational direction.
DRIVETRAIN COMPONENT
A drivetrain component provides an electronically controlled, overrunning drivetrain disconnect, such as a differential with different operating modes. The drivetrain component includes a case having an annular wall portion with a plurality of pockets in one side. The carrier is supported for movement relative to and independently of the case. The carrier includes a notch plate. The differential gear set has a pinion shaft tied to the carrier, pinion gears mounted on the pinion shaft, differential gears engaging the pinion gears, and differential gear shafts connected to the differential gears. The drivetrain component includes a first locking structure and a second locking structure. Both the first and second locking structures are on the same side of the notch plate. The first locking structure couples the case to the carrier for torque transmission from the case to the carrier in a first direction only, wherein the first locking structure does not inhibit carrier rotation in a second direction.
COUPLING ASSEMBLY WITH DETENT MECHANISM
A coupling assembly includes a multiple-position actuation mechanism and a detent assembly holding the actuation mechanism in a discrete position. The detent assembly may include a mechanical detent. In one example, the mechanical detent engages the actuation mechanism and holds the actuation member in a neutral or middle position.
Fixation structure for selectable one-way clutch
A fixation structure for a selectable one-way clutch is provided. The fixation structure comprises: a stationary member in which the pocket plate is held coaxially; a projection formed on the pocket plate protruding radially outwardly; a spline groove formed in the stationary member to which the projection is inserted while keeping a predetermined clearance in a circumferential direction; and an elastic member that is interposed between the projection and the spline groove to push the projection in a direction that the strut held in an upper side of the pocket is moved toward the notch.
Clutch assembly having normally on strut configured to prevent shock load deployment
A clutch assembly that includes an actuator, an apply spring, a pocket plate, which has a pocket, and a strut (e.g., a teeter-totter strut) retained in the pocket, is provided. The apply spring continually acts on the strut for the strut to be in an engaged position. The strut, in response to the actuator additionally acting on the strut, pivots from the engaged position to a disengaged position. The clutch assembly is configured to prevent unintended deployment of the strut due to shock load so that, when the strut is in the disengaged position due to the actuator additionally acting on the strut, the clutch assembly prevents the shock load from causing the strut to pivot from the disengaged position to the engaged position.
ONE-WAY CLUTCH ASSEMBLY AND COUPLING MEMBER FOR THEREIN WHEREIN LOCKING MEMBER DYNAMICS WITH RESPECT TO STRUT LAYDOWN SPEED ARE ENHANCED
A coupling member for an engageable coupling assembly includes a coupling face having at least one pocket. Each pocket is sized and shaped to receive and nominally retain a locking member that lays down in its pocket during an overrunning condition of the assembly at a laydown angular velocity of the coupling member about a rotational axis of the assembly. Each pocket has a pocket axis which is angled with respect to a normal to a centerline of the coupling member to improve locking member dynamics with regards to strut laydown speed during the overrunning condition.
Actuator controller to controllably supply DC power to a bi-directional electromechanical actuator
An actuator controller to controllably supply DC power to a bi-directional electromechanical actuator is provided. The controller includes a first circuit to receive power and direction command signals from a remote electronic control unit through a vehicle-based bus. Control logic is operative to determine a vehicle system failure and to generate a failsafe position command signal in the event of the failure. A failsafe power circuit controllably stores electrical power and supplies the stored electrical power based on the failsafe position command signal. A power switching and supply circuit supplies DC power of a desired polarity to the electromechanical actuator in response to the power and direction command signals in the absence of the failure and supplies the stored electrical power to the electromechanical actuator in the event of the failure.
